I would say save it until you clear act 5 100%, you will get 2 class AG, you might get Mystic out of them, which will be the best for you.
for me in Mystic, the top 3 are Magik > GR > Voodoo.
your choice after all
Ive cleared act 5 and easy path lab, unfortunately I didnt pull a mystic gem. I ended up getting 1 generic 5* gem, 1 science 5* gem, 1 mutant 5* gem and 1 cosmic 5. I guess I'll probably end up saving.

Sparky doesn't require a dupe as he's really good anyway, voodoo needs a dupe, blade, if you want the regen then yes but he's good without it, there's plenty of 5* out there now who doesn't need dupes or who do. If you're close to another 5* then I'd hold off on awakening anyone until that's opened as it could be someone who you have yet to obtain
GR is perfectly fine unduped. His sig is just another judgement that gives more damage. The mephisto GR synergy can cover that damage boost for ya. Save for 5* doctor voodoo or others who can give you more benefits
One good thing about ghost rider I'd that he doesn't need to be awakened to be good. Awakening him gives him a small bonus, but he certainly isn't worth a generic gem.

I think I would only use a class on him if I already had blade duped.
